Abstract (en)
[origin: WO0017851A1] A pre-fabricated stage (10) comprising an integrated visible light-source (64; 92; 164), means (66, 68; 96, 102; 166, 168, 202) for directing light from the visible light source away from the stage in the form of a beam of light (74; 174), and corresponding light-detecting means (75; 206) for detecting such light that is retroflected back towards the stage. Said stage (10) is typically adapted to support the weight of at least one person, and preferably further incorporates a pulse generator (86) associated with each light-detecting means, and means (104) for generating an electronic instruction code, such, for example, as a MIDI compatible code, in response to an input from the/each pulse generator for controlling a sound generator or other device. Thus, a person using the stage may play music or control other devices by cutting beams of light directed by the directing means (66, 68; 96, 102; 166, 168, 202) with his/her hands or other parts of the body. Advantageously, the pre-fabricated stage may further comprise an integrated sound generator (106), such as a sound module, and a public address system. In order to facilitate transportation of the stage, the stage may be constructed from a plurality of pre-fabricated staging components (114). The pre-fabricated stage of the invention is thus convenient to transport and simple to assemble and use by non-expert users.
